There is no such thing as an 11k watch, there are only idiots that would pay 11k for a 12 dollar watch.
In the case of the Apple Watch there is one watch with many prices based on type case and band are chose, but you get exactly the same watch in any of the models.
By the way Rolex and other high end watches sell for much more that 11k and none of them tell time better than any other $2.00 watch.
They do, however, last a heck of a lot longer than any $2.00 watch.
“In the case of the Apple Watch there is one watch with many prices based on type case and band are chose, but you get exactly the same watch in any of the models.”
That may not be true. There is speculation than the high-end Apple Watches have different internals, workers have noticed differences, specifically an additional interface on the side of the mechanism. Here is one article speculating that Apple intentionally made them upgradeable so internals can be upgraded or swapped out of expensive cases.
